Genes affected

JUP (HGNC:6207): (junction plakoglobin) This gene encodes a major cytoplasmic protein which is the only known constituent common to submembranous plaques of both desmosomes and intermediate junctions. This protein forms distinct complexes with cadherins and desmosomal cadherins and is a member of the catenin family since it contains a distinct repeating amino acid motif called the armadillo repeat. Mutation in this gene has been associated with Naxos disease. Alternative splicing occurs in this gene; however, not all transcripts have been fully described. [provided by RefSeq, Jul 2008]

The c.116_118delGCA variant (also known as p.S39del) is located in coding exon 1 of the JUP gene. This variant results from an in-frame GCA deletion at nucleotide positions 116 to 118. This results in the in-frame deletion of a serine at codon 39. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive (Choi Y et al. PLoS ONE. 2012; 7(10):e46688). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Collection Method:clinical testing

This variant, c.116_118delGCA, results in the deletion of 1 amino acid of the JUP protein (p.Ser39del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs782751782, ExAC 0.002%). This variant has not been reported in the literature in individuals with JUP-related disease. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acid is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
